    Frequently Asked Questions

    How do I select multiple PDFs at once?
    In the file picker, hold Ctrl (Windows/Linux) or Cmd (Mac) while clicking each file, or hold Shift to select a range. You can also click "Add More" multiple times to add files in separate batches.
    Are my PDFs uploaded to a server?
    No. Everything runs locally in your browser using the pdf-lib JavaScript library. Your files never leave your device.
    Will the output have watermarks?
    Never. FreeSnapTools does not add any watermarks or branding to your documents.
